[rkward-devel] rkward crashes R backend

[Maureen Allyn]

Dear Thomas,

Thanks for the very clear and prompt reply to my query. 

I will try compiling RKWard .  From your code snippet it is apparent you
require CMAKE.  Is there a version requirement for CMAKE?  I am currently
running cmake 3.3.1.

I too thought that a version mismatch might be the problem, and I tried to
compile R with --enable-R-shlib switch. So, I got a copy of R-3.2.2. (64
bit) and tried compiling from source. Unfortunately, the "sudo make install"
step failed with an error message "cannot stat NEWS.pdf: no such file or
directory".  I don't know what to do with this.   Perhaps try compiling an
earlier version than 3.2.2? 

Would installing R from Michael Rutter's archive avoid the "--enable-R-shlib
problem"?  Must the  --enable-R-shlib ALWAYS be set in order for RKWard to
function?  (Or R-studio, for that matter).

Thank you,

Mark

this sounds like a version mismatch problem. In general, you should try to
make sure to use a version of RKWard that was compiled specifically for the
version of R in use.

This is a bit of guesswork, but it sounds like the R version on the former
system is a development/SVN snapshot. In this case, your only safe bet will
be to compile RKWard from source, too. Fortunately, this is relatively easy
on Ubuntu:

sudo apt-get build-dep rkward
xzf rkward-0.6.3.tar.gz    # get it from http://rkward.kde.org/download
cd rkward-0.6.3
mkdir build; cd build
cmake .. -DCMAKE_INSTALL_PREFIX=/usr -DR_EXECUTABLE=/your/path/to/R make
sudo make install

BTW, my very first guess would be that this version of R was compiled
without the --enable-R-shlib configure option. In this case, you will have
to recompile it with the option enabled.

A different, and very comfortable way to use RKWard with a fresh version of
R is installing R from Michael Rutter's archive:
https://launchpad.net/~marutter/+archive/ubuntu/rrutter
and a matching version of RKWard from one of our "CRAN version of R"
PPAs:
https://launchpad.net/~rkward-devel

Probably this is what you have on the 32bit box(?).

If I guessed all wrong, a sessionInfo() of the R version on the crashing
machine might be helpful.

Thanks for the praise. Hope this helps some. For follow-up questions, please
post to rkward-devel at kde.org (we have moved).
